PSLE Ivory had a rectangular piece of paper, 56 cm by 34.4 cm. She cut out as many squares as possible from the paper. The side of each square was 4 cm.
- How many squares did Ivory cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 34.4 ÷ 4
= 8 r 2.4
Number of squares that can be cut out lengthwise
= 56 ÷ 4
= 14 r 0
Total number of squares
= 14 x 8
= 112
(b)
Remaining breadth of the paper left = 2.4 cm
Area of the paper left
= 56 x 2.4
= 134.4 cm
2 Answer(s): (a) 112; (b) 134.4 cm
